For the cardamom curd dumplings, beat the egg whites to a snow. Mix the curd with the yolks, semolina, cardamom and a pinch of salt with a mixer, fold in the snow and let it rest for at least 30 minutes.
The consistency of the dough should be rather soft, but firm enough to form dumplings. Bring salted water to a boil. Form dumplings from the dough with two tablespoons and place them in the boiling salted water.
Cook for about 8 – 10 minutes (must float to the top.).
Puree the mango with a blender. Arrange the mango puree on a plate and place the dumplings on top, sprinkle with the maple sugar and some cardamom.
